Questions about PWAs

PWAs do not Hide your device name or IP, from the service you are using the PWA for. TO acheave something like that you would need to employ external tools like a VPN to Hide your real IP from the service provider/PWA website.

From my understanding, one of the main security advantages of PWAs is attack surface reduction, as moving some applications which already connected to the web intro a web browser instead of giving them their own “native" applications” reduces the exploitable code run on a local system.
